dc.description.abstractThe significant strengthening of selectively laser melted (SLM) 304L stainless steel that occurs due to high-pressure torsion (HPT) is examined by recourse to detailed nanomechanical and microstructural characterization. In the as-built alloy, dislocation hardening is the main strengthening mechanism. After HPT, however, the synergistic combination grain refinement and martensitic transformation dominate the strength of the alloy. In the nanocrystalline regime, the dominance of the grain boundary-mediated plasticity retards the martensite-induced hardening.en_US
dc.description.sponsorshipThe work at Chungnam National University was supported by the National Research Foundation of Korea (NRF) grants funded by the Korea government (MSIT) (No. 2021R1F1A1048393). The work at Hanyang University was supported by the NRF grants (No. 2020R1A2B5B01001446 and No. 2020R1A5A6017701). The work at Nanyang Technological University was supported by Agency for Science, Technology and Research (A* STAR) of Singapore via the Structural Metal Alloys Programme (No. A18B1b0061). The work at Universitat der Bundeswehr Munchen was supported by Deutsche Forschungsgemeinschaft (DFG) in the framework of the priority program "SPP 2006"(No. JA 2482/3-2). The work at NIMS was supported by a Grant-in-Aid for Scientific Research on Innovative Area, "High-Entropy Alloys-Science of New Class of Materials Based on Elemental Multiplicity and Heterogeneity" through MEXT, Japan (No. 18H05451). We thank Mr. Cheol-Hwee Shim at KIST for the ASTAR-TEM operation.en_US
